9 Compound light microscope: -light must pass through thediaphragm and through theobject.-object must be “thin” ortransparent so the light canpass through it.
10 StainingIs a method of adding color to a cell so that the cell and its structures can be seen more clearly through a microscope.
11 Limit of ResolutionThe limit of resolution is the point at which you see an item most clearly.Any magnification above or below that point will results in the object looking blurry.
12 Type 2: Stereoscope-Used to view the surface of objects which are too large for light to pass through them.-Uses to lights to illuminate the surface of the object.-Stereo means“3 dimensional”-Provides a 3-D detailed look at the surface of an object.
14 -look through2 ocular lenses-magnifies between x10 to x60
15 Type 3: Electron Microscopes Uses electrons to form an image and NOT lightHas a very high limit of resolution.-can see items very clearly at any magnification-can magnify up to 500,000x and still be clearObject is placed in a vacuumNo airNo oxygenOrganism is DEAD
16 Two types of electron microscopes: 1. T.E.M. ~ Transmission Electron MicroscopeProduces a 2-D, black and white image of inside of a cell.
